A Zarya Antenna is a special type of directional mediumwave broadcasting antenna consisting of a long straight row of grounded lattice towers with a height of approximate 50 metres in a distance of 100 metres. These towers carry the antenna wire.
Three types of Zarya antennas, which exist at most larger AM broadcasting facilities in former Soviet Union, are used. They use some configuration but different length values, which are 1500, 2500 and 3500 metres.
